Abstract
Silicon carbide whiskers, a strong material that resembles cat's whiskers, are produced, primarily, for strengthening ceramics and metals. The current method for producing these whiskers is to use a semibatch process, extremely difficult to model mathematically. An alternative model utilizes the expertise of operators accumulated from years of experience in initializing and running the process. We designed two expert systems in which the process can be set up and run by nonexperts. One system uses crisp logic and the other fuzzy logic. In this article, we compare the two systems.
